THE PRINCIPLES, ALGORITHMS FOR MODELING AND RESEARCH OF ENERGY PROCESSES IN SWITCHED-MODE MODULAR DC-DC CONVERTERS

Abstract

The principles and algorithms are proposed for modeling and research of energy processes in pulsed DC converter module structure with single-phase and multi-phase conversion with boundary mode operation for the eight options of widely used types of circuit implementation of the power channels (decreased, increased, inverting, with direct switching diode, with reverse switching diode, with the withdrawal of the transformer mid-point, bridge and half-bridge). Systematic mathematical models are proposed (generalized to the types of power channels and the principle of single-phase and multiphase transformation) of electric and energy processes in pulsed DC converter module structure for stabilization and tracking modes of boundary inductive currents of smoothing filters in power channels that lye in the base of computational modeling of the proposed principles of energy processes used to solve problems of research and design. The principles and the algorithms of software modules for the solution individual problems (operating current, power, energy losses, the efficiency), and multifunction module software with enhanced functionality are proposed
